Input pins become high-impedance, and output pins retain their state.
Notes: 1. When the Hi-Z bit in SBYCR is set to 1, the output pins enter their high-impedance
state.
2. This pin operates as an input pin during power-on reset period. This pin should be
pulled up to prevent malfunction. In this case, the resistance value must be 1MΩ or
higher.
3. This pin operates as an input pin when the IRQEL bit in SBYCR is set to 0.
4. This pin operates as an input pin when the IRQEH bit in SBYCR is set to 0.
5. This pin becomes high-impedance in the emulator.
6. In the emulator, this pin operates as an input pin when the Hi-Z bit in SBYCR is set to 0.
